Role of MAPKs in HSP70’s Protection against Heat Stress-Induced Injury in Rat Small Intestine

Figure 3

Effects of HSP70 inhibition on the jejunal morphology of heat stressed rats. The experiment lasted for 14 days with daily 50 min of heat stress treatment (43°C) for the HS and HQ groups. Rats of HQ group were intragastrically given 0.5 mL quercetin solution (50 mg/kg body weight) before the heat stress treatment. The jejunum from rats in the CON, HS, or HQ groups on days 7 and 14 of heat stress was examined by hematoxylin-eosin staining. Scale bar = 100 μm. CON: control; HS: heat stress; HQ: heat stress + quercetin.
